Brought my laptop by because the fans were loudly buzzing and overheating. They diagnosed it by the next day, attempted to clean the fans but they were coated in dust so they ordered new fans for it and installed it. Cost me 180$ and took 5 business days, very worth it. I can't even hear the fans when the laptop is running, and the temperature of my laptop has gone down a lot.
